The housing stock
What we are usually working with in Belvedere
Windows sit in deep concrete reveals with a cast sill, and that reveal is usually the least square thing in the room. Almost everything that makes a fitting day hard is a property of the building rather than of the stone. The first hour is protection and packing, not stone.
The split between the hill and the flat riverside changes the job entirely, establish which end of Belvedere you're quoting before assuming driveway access. A hard climb from the riverside up to the higher roads, with plenty of houses set above the pavement behind steps; the lower estates have parking courts and rear access paths.
Door openings and the hall were set to a generous standard, so a long piece turns in from the front without being stood on end to do it. Fixings into concrete go in with proper anchors, and the dust is contained rather than swept up afterwards. Old fabric gets handled as old fabric.
Around here the stock is Victorian villa, 1930s semi, postwar council estate and 1960s flats. They were built to different tolerances, and the stone has to absorb that.
There is nothing to visit in Belvedere. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
